Application filed September 7, 1920. Serial No. 408,557.

a flier ofnovel construction, which has the appearance of the standarddrop forged flier now commonly used, and also has the desirable featuresof the latter, and possesses in addition advantageous features, as willbe described, whereby a superior fliermay be provided at a minimum costand in a mini- To this end the flier is provided with a solid metalmember which forms one arm of the flier, and a hollow sheet metal memberwhich forms the other arm of the flier and is firmly connected withthesolid metal mom her and reinforced by the latter to withstand the strainofcentrifugal'force while in use. The flier is further provided with ahub of novel construction, for the reception of the s indle.

These and other features of this invention will be pointed out in theclaims at the end of this specification. i

Referring to the drawings, or represents the solid metal member, I)the'hollow sheet metal member, 0 the hub, and d the key for engagingthespindle (not shown) but with which the hub e cooperates in a manner wellunderstood. The solid metal member a, shown separately in Fig. 8, ispreferably forged from a steel rod'or bar andis shaped to form an armhaving a substantially straight portion 10, preferably oval in crosssection, and .a curved upper portion 12,

which latter is integral with a substantially flat center portion 13forming asupporting member for the hub 0, and from which extends ashorter curved arm 14, of substantially the same curvature as the curvedportion 12 and diametrically opposite thereto. The curved arm 1 1 isprovided with a concaved outer surface 15 into which is fitted acorrespondingly curved upper portion 16 of the hollow metal arm b, whoselower portion 17 is substantially straight and preferably round in crosssection.

.The'hollow metal arm 6 is made from a flat blank or piece of sheetmetal, preferably cold rolled steel, which is provided with smooth upperand lower surfaces free from scale, burs or the like.

The metal blank is curved at its upper endto conform to the curve of theshorter arm 14, and after being fitted to the arm li, is electricallywelded or otherwise firmly secured to the arm 14. At the same time thesheet metal blank is welded to the shorter arm 14: of the solid membera, a lug 20 is also welded to the outer side of the blank at a suitabledistance from the upper curved end thereof so as to cooperate with a lug21 at the end of the shorter arm 14512-0 form a mounting for the usualpresser employed .the blank in close proximity to eachother to form thehollow arm 5 and provide the latter with a longitudinally extended slot25. The sheet metal blank is made of suitable shape and width to providethe hollow arm 6 with a larger or wider upper curved end portion, whichdecreases in size or diameter from its end 26 to the straight portlon 17of said hollow arm. In the present instance, the hollow arm 6 is locatedwholly on one side of the center or supporting portion 13 of the solidarm a, and is provided with a finger 27 which projects beyond the openupper end 26 of the hollow arm and abuts against a shoulder 28 on thesupporting portion 13 of the solid member, and is of substantially thethickness of said shoulder so as to have its upper surface substantiallyflush with the upper surface of the supporting portion 13, as shown inFig. 1. While this construction may be preferred, it is-not desired tolimit the invention in this respect.

After the hollow arm I) has been formed as described, the grooves oropenings which are found between the hollow arm Z) and the side edges ofthe shorter arm 14 of the solid member a, may and preferably will befilled with hard solder or other suitable material, which filling 30 isrepresented in Figs. 6 and 7, and by means of said filling a smoothexternal surface for the hollow arm Z) and solid arm 14 may be obtained.

After the solid and hollow arms a, b have been welded or otherwisefirmly secured together, a hole 31 is drilled in the supporting portion13 at the center of the fiier, for the reception of the hub c, which ismade from solid stock on a screw machine or automatic lathe andtherefore rapidly produced. The hub c is provided with a cylindricallower portion 33 whose external diameter is substantially the same asthat of the opening 31, and with a head 34 of larger diameter whichforms an annular shoulder 35 which rests upon the upper surface of thesupporting portion 13 of the solid member a.

The hub 0 may be threaded into the opening and the threads rusted in orit may be electrically welded or otherwise firmly secur d to .thebearing member 13. The hub c is preferably provided with a tapering bore37, which gradually tapers from the lower end of the hub to near theupper end thereof and with which communicates a smaller opening 38 inthe upper end of the head 3% and a lateral opening 39, for the passageof the roving through the opening 38 into the head 34 and out therefromthrough the lateral opening 89 into the hollow arm I), from which itpasses out through the slot 25 at some portion of the length thereof ina manner well understood.

After the hub 0 has been fastened to the solid arm a, a hole or openingis broached or otherwise formed in the bearing portion 13 of the solidmember a and in the hub c, for the reception of the key d, which engagesa slot in the upper end of the spindle (not shown), so that the lattermay drive the flier in a manner well understood.

The shorter arm 14 of the solid member a is preferably made of greaterthickness adjacent the bearing portion 13 and tapers toward the centerof said arm, as shown in Figs. 1, 3, 6 and 7, which increased thick nessacts to reinforce the curved upper portion of the hollow member so as toenable the hollow member to withstand the strain of centrifugal force atordinary speeds of use, which usually ranges from 1000 to 14200revolutions of the flier per minute.

The hollow sheet metal member Z) and the solid member a are properlyproportioned so that in the finished flier, a perfect balance betweenthe arms of the flier is obtained.

By welding the sheet metal blank to the solid member and welding the hubor lug 20 to the said blank before the latter is closed to form thehollow arm, any scale, burs or rough spots on the surface of the blankwhich ultimately forms the inner surface of the hollow arm, can bereadily removed as such scale, etc., are freely accessible to theworkman.

It is prefererd to make the hollow memher from cold rolled sheet steelas the latter is normally provided with a perfectly smooth surface. Itis also prefererd to use hard solder to fill the joints between thehollow member 6 and the edges of the shorter arm 14 of the solid member,as the heat required to melt the hard solder is not sullicient to causescale to be formed on the in ner or upper surface of the sheet metalblank, and if scale should be formed by application of too great a heat,it is accessible and can be readily removed, as above pointed out.

Furthermore, the hard solder can be quickly ground off and polished, andthe joint rendered invisible by nickel plating. It is prefererd tonickel plate or othcrwi;-:c treat the finished flier so as to preventrusting, due to the operators handling the fliers with moistened hands,especially in warm climates.

The finished flier represented in Fig. l and composed of a solid metalmember and hollow sheet metal member has substantially the sameappearance as the solid one piece flier now imported into this country,and therefore is not open to objection by the workmen who are usuallyforeigners and naturally would be prejudiced against fliers which differradically in appearance and construction from those with which they arefamiliar.

Furthermore, the fiiers embodying this invention can be made in aminimum time and at a minimum expense, so that they can be provided insufficient quantities and at such cost as to satisfy the demand for thesame.

In the present instance a preferred construction of flier is shown, butit is not desired to limit the invention to the particular constructionshown.

The supporting member 13 is preferably provided on its under surface onopposite sides of the center opening 31 with depressions or sockets 50for the reception of molten metal which serves to secure the hub c tothe supporting member and to strengthen the latter, especially so as towithstand the strains of centrifugal force.
